اثر ترکیب لیزرهای هلیوم- نئون و دیود بر تولید آنتوسیانین و رشد سلول در کشت سوسپانسیون سیب گوشت قرمز (Malus sp.)

The red-fleshed apples are from varieties of apples confer the competence and high ability in vitro to produce anthocyanins in their organs. Several factors affect the in vitro production of anthocyanins in plant tissue culture and to produce high, the optimizing of these factors are very necessary. Light is one of the most important factors that many studies have been done in this area but the laser irradiation effects has not been investigated. We have studied the effect of combine lasers treatment of He-Ne with diode on in vitro production anthocyanin and cellular growth of cell suspension of red-fleshed apple. This experiment with 18 combinations treatments (blue laser at the intensities of 67.09, 32.74, 30.4 and 13.73 mW/cm2 and a red laser at the intensities of 6.46, 4.82, 1.54 and 0.666 mW/cm2 and two controls including darkness and fluorescent light) as a factorial design based on CRD with three replications for each treatment were applied.With increasing of combination lasers radiation intensity, production rates monomeric total anthocyanins (TMA) and total anthocyanins (TA) increased but lead to was reduced the cell growth. Results of this work showed that probably high intensity of combination lasers radiation treatments as a stress factor made decreased cell growth and induced high concentration of anthocyanins in the cell exposed to stress and good for decreasing injures proceed from stress and also lead to persevered cell of red-fleshed apple through high concentration accumulation of anthocyanin in vacuole.
